INSTALLATION CHECKOUT

Carefully complete the following checkout procedure before operating

the vehicle. If a step does not test correctly, use the troubleshooting guide

(Section 5) to identify the problem.

Put the vehicle up on blocks to get the drive wheels off

the ground before beginning these tests.

Don’t let anyone stand in front of or behind the vehicle

during the checkout.

Make sure the keyswitch is off and the vehicle is in

neutral before beginning.

Wear safety glasses and use well-insulated tools.

A. Connect the battery. Use a voltmeter to verify that the proper voltage

and polarity appears at the battery B+ and B- terminals.

B. Check the voltage at the controller B+ and B- bus bars. If your

system has a precharge resistor in parallel with the main contactor, you

should see approximately 90% of the full battery voltage. If your system

does not have a resistor, temporarily connect one (100 to 200 ohms, 5

watts, or a 100 watt light bulb). The voltage at the controller should rise

to approximately 90% of the full battery voltage.

C. If “A” and “B” do not check out, troubleshoot the wiring connec

tions. Do not turn on the keyswitch until the trouble is corrected and

“A” and “B” check out.

D. With the forward/reverse switch in neutral, turn on the keyswitch. If

the motor runs without the throttle being applied, turn the keyswitch off

and recheck the wiring. If the motor does

not run without the throttle

applied, proceed with the checkout. Select a direction and slowly apply

the throttle; the motor should now respond.

E. Look to see which direction the wheels are turning. If the wheels

are going the wrong way, turn everything off and interchange the motor

ﬁeld connections.

F. If you have HPD, check it next. Turn off the keyswitch and direc

tion switch. Apply the throttle, turn the keyswitch on, and then select a
